Ok, I already know how to hide my program from Ctrl-Alt-Delete. Now I need to either 1. Hide My Program from running processes or 2. Disallow Termination of my Application. My app is a security application so I can't let the user trying to wreck the machine to kill my app. For demonstration purposes of this problem get TaskInfo2000 program and then create a small exe. Run both programs and terminate the process with TaskInfo2000. Now, try and prevent it from happening. Please help me with this! I've been everywhere and no one really has any answers. Thanks!
